Q: I committed my self more than once to avoid a certain act but, unfortunately, I did not fulfill this commitment. Please advise me and whoever acts likewise.
A: This needs elaboration; if you have committed yourself to refrain from doing what Allah (Exalted be He) has prohibited, you should repent to Allah (Exalted be He) and revert to Him, for whoever repents, Allah will accept their Tawbah (repentance).
